24: Heating system upgrades + woodworking
Well, I'm finally
back in the saddle -- making furniture. Since Sunday I have
made 6 mirrors
and 1 table for the upcoming Fine
Furnishings Show
in Providence. It has been great to work into the night
when it is in
the low 40's outside and not even know it. I'm working in
my T-shirt just
like I did in California!
I took a break
from wood working this afternoon to do some system
upgrades.
I added a pump with it's own seperate solar panel to
circulate the
water through the heat exchanger. The new pump
is in the center
of the image below:
(Note: I later learned that I had mounted the pump
wrong.
It should have it's axis horizontal to prevent wear
on it's bushings. I changed it later)
|
NOTE! If you are building a system like mine that has circulation pumps that run on solar panels, I am producing an inexpensive Differential Temperature Controller that runs on solar power. It will increase your system efficiency significantly. |
And I added another
thermometer so I can see how hot the solar heated
water is before
it goes to the propane heater. Not enough
sun today to
run the solar side, but the day has been quite
warm anyway.
The leaves are
at their peak on our property -- the grove of aspens
has hit the perfect
yellow:
Oh, and here's
a picture that I took for the article I'm writing about
my solar project
for Home Power Magazine.
It will be printed in
the June/July
issue. Dowload it here.
